He'd be a good squad signing. His passing is great and he'd work well in a back three when required. If he moves to City then it's a sensible move for both parties. He's also better on the ball than Stones, for what it's worth.
Let's not start the whole "we shouldn't have sold him" lark, mind you. He was shite during his final season here and was shown the door as a result. If we were similarly ruthless with other players previously (and still?) at the club we'd probably be in a better position right now.
